I am betting when Wolverine encounter mystercial balde and gets ass beaten he has hallunciation of Jean.

They did exactly this in a 3 part Larry Hama Wolverine story, where Logan was stabbed through the chest with a samurai sword by a Yakuza guy( I think the sword had mystical properties), and had a 'near death experience', where he encountered JG in the afterlife, before awakening and clawing out of his own grave.
They also used this scenario in the Civil War storyline, where Logan again encountered JG in the afterlife, when he was burnt alive and almost died.
